About Vial Tool.
Built because the "microdosing chart" everyone searches for assumes a vial and water volume that probably aren't yours.
Who
Vial Tool is built and maintained by the team behind Peptides Uncaged, an independent peptide vendor-review site, and its sister sites. It exists because the single most useful thing in the category — the dose-to-units arithmetic — was scattered across forum screenshots and clinic blogs that stop one sentence short of a number.
How it makes money
One way: when you click through to the vendor we buy from and order, we earn a commission. The code is SHAUN10. That's disclosed on every page. It doesn't change any number the calculator produces, and there are no ads, no account, and no data sold.
What it won't do
Recommend a compound. Recommend a dose. Tell you whether to use anything. The quick-fill chips are numbers people commonly search for, labelled as such, not suggestions. If a page here ever reads like advice, that's a mistake — tell us and we'll fix it.
Report a math error
The formula is public and simple: units = (mg ÷ (vial mg ÷ water mL)) × 100. If you find a case where the tool disagrees with that, email the inputs and we'll fix it the same day.
Privacy
Saved setups live in your browser's local storage and never leave your device. Analytics are aggregate (page views, which compound was calculated, whether the vendor link was clicked). No dose you enter is ever sent anywhere.
